Specification of Letters Patent. Patented June 10, 1919,

Application l'ed May 5, 1917. Serial No. 166,636.

T0 all 'whom t may concern Be it known thatI, ALEXANDER THnoDoRn MINTY, citizen of the Dominion of Canada, residing at the city of Brandon, in the Province'of Manitoba, in the Dominion of Canada,'have invented certain new and useful Improvements in Harrow-Carts, of which the following is a specication.

This invention relates to vehicles used in connection with the ordinary drag harrow,

and the objects of the invention are first, to providea cart of simple and inexpensive construction providing novel means whereby a plurality of harrows `may be attached thereto, second, to provide means for raising any harrow independently of the others to relieve it from accumulated trash, third to provide means to render the harrows inoperative while being moved from place to place, and fourth, to provide means to steady the structure while moving or at work and to prevent the draft animals from stepping back into the harrows.

The means by which these and certain other objects of the invention, which will appear as the description proceeds, are attained, will be found fully described in the following specification and then more particularly pointed out in the appended claims, `reference Valso being had to the drawings forming part hereof in which similar characters of reference refer to similar parts throughout the different views, and in which,

Figure l is a plan view of a cart embodying the invention, and having a plurality of harrows connected therewith.

Fig. 2 is a view of the cart with one wheel removed and showing by dotted lines one of theharrows in raised position.

Fig. 3 is a fragment of the, draw bar.

Fig. 4 is an enlarged view of the hinge by which one of the tongues is secured to the cart.

Fig. 5 shows the shaped to pivotally connect shown in Fig. 4.

Fig. 6 is a central fragment of the axle without the seat and showing the truss used to support the axle andthe hooks by which the rear ends of the harrows are carried when being moved from place to place.

Fig. 7 shows one of the lifting levers and the clip by which it is carried'from the axle.

Fig. 8 is one of the eye bolts removed from the draw bar.

In carrying out end of one of the tongues with thehinge my invention I prefer to use a tubular axle 1 having-the wheels 2 of suitable size rotatably mounted thereon at each end, and truss rods 3 and 4 ruiming from end to end and under the bridge 5 which spaces the rods from each other as shown in Fig. 2 and supports the axle at the center. A seat 6 for the driver is provided directly over the bridge 5.

A draw bar 7 preferably also tubular normally rests upon the ground some distance in advance of the axle, and brace rods or tubes 8 extend between and connect the axle and draw bar at each end, these connections being preferably made by means of interiorly threaded pipe fittings 9 of the ordinary T type.

The connecting members may be secured in position by pins 10 which pass through the members they connect.

The draw bar 7 is provided with a plurality of eye bolts 11 which pass through the same and are secured in position vby the nuts 12.

Four of the bolts are preferably provided for each harrow and they are positioned so that the links 18 on the harrows 14 will come just within the outer two of the group, and a bolt 15 is then'passed through the eyes in the bolts 11 and the links 13 on the harrows, thus flexibly connecting the harrow with the draw bar ina manner preventing it from encroaching upon the ground occupied by the neighboring harrows in the gang.

It will be noted that a separate bolt 15 is provided for each of the harrows 14 so that any harrow in the gang may be disconnected without disturbing the remainder.

It is a well known fact that the teeth of all harrows become fouled from time to time with weeds and trash and require to be relieved by lifting. To perform this operation a lever is provided for each harrow, this in each case consisting of a handle portion 16 standing up beside the seat 6, a lateral portion 17 extending to a position over the harrow section to which it pertains, and a forwardly projecting arm 18 having a chain 19 at its outer end connecting with theA harrow section adjacent'the rear end thereof.

' The horizontal portions 17 of the levers are rotatably supported in bearings indicated as 20, 21 and 22 clipped on the axle 1 and pinned thereto to preserve their position. It will be noted that in the present from the handle of the seat tooperate butV one.

case, as there are'six harrow sections shown, and as three levers are required on each side them,- the clips 20 being those closest to the seat on each side, are shaped to accommodate all three levers, while those 2l support two, and those 22 'In this manner each lever is supported from the axle immediately above the section it is designed to operate, and its chain 19 connects it leither directly with the liarrow section, or with a cross bar 23 secured .to the harrow for the purpose.

. the rear of the harrow When any harrow becomes Vfouled it is only necessary for the operator to pull ,the particular lever connected therewith to raise to the position indicated by the dotted lines in Fig. 2 when the .objectionable matter falls from the teeth.

V A p air of tongues 24 :and 2,5 form a novel part of thestructure, these being positioned equi-distant from a. .central line passing through the seat 6 and yspaced to permit of two horses being hitched between them.

i The inner endsk oi' ,the tongues are pivotally ands 28 secured to the draw bar connected for vertical movement -to blocks 26 which in turn are hinge connected for lateral movement .to the frames 27 on the structure formed from the verticalstand- 7, and the curved brace members 29 which support the vstandards from the ,axle l.

Thus it will be seen that the tongues have freedom yof movement both laterally and yertically as indicated by the dotted lines in y .and 32 n; ine

and perform nov function toward the guiding of the cart.

:As .evener 30 is secured by the chains 3l opposite ends thereof, to the draw bar 7, and whiiiletrees, .83 provide means, inA the present case, whereby six horses may be hitched to theevener bar, to

Vdraw the narrows and cant.

A plurality of long hooks 34 are swin-g- -ingly secured to the axle l and provide `means whereby the rear ends .of .the harrow -sections'may be hung up ,and the harrows .-rendered inoperative Awhen it is (desired to vdieated by the position move them from place to place:

In operation the horses ,are hitched as inof the whi'i'lietrees in YFigi-l, and as those nearest the tongues ,24

Y Vand 25 are connected therewith in the usual man-ner Iby neck yokes or breast straps, the

From the foregoing description it will be seen that my invention notonly provides means whereby the operator may lride dur'- ing the operation of harrowing, which is the function of the Ordinary harrow cart, but through the operation ofthe `draw bar provides for a better performance of Ythe operation .of harrowing, by maintaining'the proper positions and preventing them from being lifted Vout of the ground.
